Post script: Koos seemingly didn't know the stock was being traded (OK, so can't prove it was being shorted on the Berlin Exchange because, you know, that is illegal. And illegal shorting doesn't take place in foreign or domestic markets, does it?) until long after it had been present on the exchange. Because investors told him so. So, investors knew, here and abroad. But, this finance guru didn't know his own stock was listed on the exchange? Uh huh.
